Illinois Representative Scott Drury (D-Highwood) has introduced HB 193. It would move the Illinois primary (including the presidential primary) from March to the 4th Tuesday in June.
Illinois and Texas are the only states in the nation in which non-presidential primaries are earlier than April. If the Illinois bill were to pass, there would be no effect on petition deadlines for independent candidates and the nominees of unqualified parties. Thanks to Josh Putnam for this news.
